There were 8 countries (Korea, China, UK, Canada, USA, Brazil, France, and Japan) with 27 representatives in attendance. The Plenary provides an opportunity to review the progress of the work items and agree to target dates for future stages of development of the documents. The following summaries are provided, based on notes taken at the meeting: Working Group 5 is targeting 2009-10 for a Draft International Standard. The work item is ISO 17268: Compressed hydrogen land vehicle connection devices.  The working group has agreed to a 70 MPa profile and decided to delete the 50 MPa profile at this time as it is not being actively used (and will likely have to be upgraded if/when there is interest in 50MPa systems).   A change to title and scope as shown in the report of the Secretariat was approved. Working Group 6 is being re-structured.  At that time, work will re-start with regard to development of an International Standard for hydrogen vehicle tanks. Working Group 8 continues to develop the International Standard for ISO 22734-2 Hydrogen generators using water electrolysis process — Part 2: Residential applications.  There is a 2009-11 target date for a Draft International Standard. The target date for the Final Draft International Standard ISO 16110-2 for hydrogen generation by fuel processors is 2009-10. This is currently in process. ISO 16111 by Working Group 10 was published.  It is now used in the Orange Book as the basis for the approval of hydrogen stored in metal hydride storage (UN3468).  Canada is likely to submit a New Work Item Proposal (NWIP) for “micro” reversible metal hydrides based on ISO 16111.  This work would be picked up by WG10. Committee Draft 20100 on filling stations was released for comment on October 6.  This Committee Draft does not reflect final recommendations from Task Group 1 and Task Group 2 with regard to setback distances and dispenser requirements. In addition to resolving the setback distances, Task Group 1 will address hydrogen venting, definition of hazardous locations (zones) and improve definition of requirements for LH2. The scope of this document is being modified to capture indoor (warehouse) fueling.  A new Task Group will be formed to address the added protective measures for this situation. Working Group 11 targets the Draft International Standard by 2010-11. Working Group 12 on hydrogen fuel quality is targeting 2010-10 for a Draft International Standard.  This working group met on October 12-13 to continue their efforts. Working Group 13 is developing ISO 26142 on hydrogen detectors. The Final Draft International Standard is targeted for 2009-11. NWIPs are being circulated for stationary hydrogen quality (Japan) and stationary storage vessels (France). There was a brief discussion of the need for component standards in the Compressed Hydrogen Storage Systems on vehicles.   ISO/TC22 would have the lead.  The US discussed the HGV standards being developed in North America for this purpose. The Chair suggested that the US-TAG should confirm CSA’s intent to promote HGV standards for this purpose and, if so, the delivery dates. The Chair noted the possibility of forming an “advisory group” on pressure vessels in the near future.  This group would provide external, as well as internal, guidance on standards. The ad hoc group on hydrogen vehicle fuel system is performing a technical consultation, and has published the findings of the review on existing standards. Membership changes of note:  Austria became an O-Member (formerly P-member); Brazil upgraded from O-membership to P-membership. The next ISO/TC 197 Plenary Meeting will be held around May 16-21, 2010 in Essen. This coincides with the 2010 World Hydrogen Energy Conference.
